Subject: [RFC] rtl8180: change PCI DMA mask to DMA_BIT_MASK(32) to solve "No suitable DMA available" problems on sparc64.
Date: Thu, 10 Sep 2009 11:37:43 +0200 [thread overview]
Message-ID: <1252575463.30576.59.camel@localhost> (raw)
Hi there
I had problems to get my rtl8185 PCI card running on Sparc64: I always
got an error about "No suitable DMA available" followed by an error
that no device could be detected. When comparing the rtl8180 driver to
others I noticed that others are mostly using DMA_BIT_MASK so I changed
the custom mask to DMA_BIT_MASK(32) which fixed my issue.
Cheers,
Tiziano
